It would be interesting to see what comes out of this - the shift lever goes in to an extension, so it's theoretically possible to "re-do" the top of the extension, making it taller, so that it could accomodate a shift lever with a higher pivot point.
My concern as such, is that even with the stock shifter, the transmission apparently does not like to be "hustled" and will click & crunch on a fast shift, I don't know if it's just my transmission or if all of them are like this, but if they are, a short shifter will just make it worse.
